Other embodiments will be apparent to those skilled in the art from consideration of the specification. The specification and examples are exemplary only.
One aspect of the utility model provides a self-pressurization gas extrusion type rail attitude control power system, which comprises a high-pressure storage tank 1, a low-pressure storage tank 2, an additional pump 3 and a gas generator 4, as shown in fig. 1. The liquid outlet of the high-pressure storage tank 1 is connected with the liquid outlet of the low-pressure storage tank 2 through a liquid path guide pipe 5, the air inlet of the high-pressure storage tank 1 is connected with the air inlet of the low-pressure storage tank 2 through an air path guide pipe 6, the low-pressure storage tank 2 is used for conveying liquid propellant to the high-pressure storage tank 1 through the liquid path guide pipe 5, and the high-pressure storage tank 1 is used for supplying the liquid propellant for the engine 11. The liquid outlet of the high-pressure storage tank 1 is respectively connected with the inlets of the booster pump 3 and the engine 11, the outlet of the booster pump 3 is connected with the gas inlet of the gas generator 4, and the gas outlet of the gas generator 4 is connected with the gas inlet of the high-pressure storage tank 1.
The gas path guide pipe 6 is provided with a gas control valve 7, and high-pressure gas in the high-pressure storage tank 1 enters the low-pressure storage tank 2 along with the gas path guide pipe 6 by opening the gas control valve 7, so that liquid propellant in the low-pressure storage tank 2 can quickly enter the high-pressure storage tank 1 under the action of high pressure. The booster pump 3 serves to feed part of the liquid propellant in the high-pressure tank 1 to the gas generator 4 so that gas generated after the liquid propellant burned via the gas generator 4 enters the high-pressure tank 1 to pressurize the high-pressure tank 1.
Specifically, the self-pressurization gas extrusion type rail attitude control power system comprises a high-pressure storage tank 1, a low-pressure storage tank 2, an additional pump 3 and a gas generator 4. By adopting the rail attitude control power system, liquid propellant can be conveyed to the high-pressure storage tank 1 through the low-pressure storage tank 2 in the working process of the system. The high-pressure storage tank 1 and the low-pressure storage tank 2 replace the original storage tank, the liquid propellant in the original storage tank is arranged in the two storage tanks, so that the design difficulty of the high-pressure storage tank is reduced (the volume is reduced, and the structural complexity is reduced), and meanwhile, the low-pressure storage tank 2 can improve the liquid propellant to the high-pressure storage tank 1 at any time according to needs, so that the use of an engine is facilitated.
In addition, through being equipped with gas control valve 7 on gas circuit pipe 6, can make the high-pressure gas in the high-pressure storage tank 1 follow gas circuit pipe 6 and get into low pressure storage tank 2 so that the liquid propellant in the low pressure storage tank 2 receives the high pressure effect and gets into in the high-pressure storage tank 1 fast, this design not only can make full use of high-pressure gas for high-pressure gas cyclic utilization, but also can improve liquid propellant's conveying efficiency, design benefit, convenient application. The whole structure has the advantages of reasonable design, convenient control and production, and effectively reduces the structural quality and the system quality of the storage tank 2 and improves the reliability of the rocket.
It is worth mentioning that in order to facilitate the low pressure tank 2 to provide the liquid propellant to the high pressure tank 1, the liquid propellant is prevented from flowing to the low pressure tank 2 due to the high pressure of the high pressure tank 1, for example, a check valve 8 may be provided in the liquid path conduit 5, so as to prevent the liquid propellant entering the high pressure tank 1 from flowing back to the low pressure tank 2, and ensure the stable pressure in the high pressure tank 1.
As shown in fig. 1 and 2, in practical use, in order to rapidly discharge the liquid propellant in the high-pressure tank 1 and the low-pressure tank 2, for example, a baffle device 9 for matching the high-pressure gas to push the liquid propellant to flow is respectively arranged at the air inlet of the high-pressure tank 1 and the air inlet end of the low-pressure tank 2 and is positioned inside the high-pressure tank 1 and the low-pressure tank 2. The inside of the storage tank is divided into two spaces by the blocking device, and the high-pressure gas can push the blocking device 9 to enable the liquid propellant inside the high-pressure storage tank 1 and the low-pressure storage tank 2 to be rapidly discharged out of the high-pressure storage tank 1 and the low-pressure storage tank 2 (for example, the blocking device of the high-pressure storage tank 1 can rapidly input the liquid propellant inside the high-pressure storage tank into an engine under the action of the high-pressure gas so as to be used by the engine), so that the output efficiency of the liquid propellant can be improved.
In addition, for convenience of using the baffle device 9, for example, the baffle device 9 is composed of a circular plate 12 with a through hole and an elastic membrane 13, and the elastic membrane 13 is connected to the upper surface of the circular plate 12 (may be designed by adhesive connection or integral molding). In order to prevent the liquid propellant from flowing out through the gaps between the inner walls of the high-pressure tank 1 and the low-pressure tank 2 and the circular plate 12, for example, the outer periphery of the circular plate 12 may be brought into close contact with the inner walls of the high-pressure tank 1 and the low-pressure tank 2 in a sealed manner. In the application process, on one hand, the elastic membrane 13 can deform after being impacted by high-pressure gas, so that the liquid propellant in the high-pressure storage tank 1 and the liquid propellant in the low-pressure storage tank 2 are pushed to flow out quickly; on the other hand, because the elastic membrane 13 has elasticity, it can be convenient for the elastic membrane 13 to reset (can resume the original state fast after the deformation takes place) when the high-pressure gas reduces to a certain extent.
It is further described that, in order to reduce the design difficulty of the high-pressure tank 1 and reduce the design requirement of the high-pressure tank 1, for example, the volume of the high-pressure tank 1 may be smaller than the volume of the low-pressure tank (for example, the tank in the prior art is 100L, after improvement, the high-pressure tank is designed to be 20L, and the low-pressure tank is designed to be 80L, that is, compared with the original 100L tank, the difficulty is reduced in both the design volume and the material application in manufacturing the 20L high-pressure tank), the design difficulty of the tank is reduced in the whole design, and meanwhile, the production is facilitated, thereby facilitating the complete machine assembly of the rocket.
In the present embodiment, in order to increase the capacity of the liquid propellant, for example, the high-pressure tank 1 and the low-pressure tank 2 are designed as cylinders. The design of the high-pressure tank 1 and the low-pressure tank 2 may be changed according to actual needs, and may be, for example, a rectangular parallelepiped or a cube, and the like.
In particular, on the premise that the pressure of the low pressure tank 2 is not affected (i.e. after the high pressure gas enters the low pressure tank 2, the internal pressure of the low pressure tank 2 reaches a specified standard, and then the gas control valve 7 is closed), in order to quickly discharge the high pressure gas, for example, a gas discharge valve is further provided on the gas path conduit 6, so that the high pressure gas is discharged from the gas path conduit 6 to the outside, and the use safety of the low pressure tank 2 is ensured.
As shown in fig. 1, in order to grasp the pressure inside the high-pressure tank 1 and the low-pressure tank 2 in time, for example, pressure sensors are provided inside the high-pressure tank 1 and the low-pressure tank 2. In addition, in order to facilitate control of the booster pump 3 and the gas control valve 7, the booster pump 3 and the gas control valve 7 may be controlled by a programmable controller, for example.
Specifically, when the pressure sensor detects that the internal pressure of the high-pressure storage tank 1 reaches a set value, the programmable controller controls the gas control valve 7 to be opened, so that high-pressure gas in the high-pressure storage tank 1 enters the low-pressure storage tank 2 along with the gas path conduit 6, and liquid propellant in the low-pressure storage tank 2 rapidly enters the high-pressure storage tank 1 under the action of high pressure (because the internal pressure of the low-pressure storage tank 2 is higher than the internal pressure of the high-pressure storage tank 1); and when the pressure in the low-pressure storage tank 2 reaches a set value measured by the pressure sensor, the programmable controller controls the gas control valve 7 to be closed, and opens the gas discharge valve 10, so that high-pressure gas is discharged along the gas discharge valve 10 (in some application occasions, the low-pressure storage tank 2 is not enough to bear the high-pressure gas in the high-pressure storage tank 1 completely).
In addition, for example, the diameters of the gas conduit 6 and the liquid conduit 5 are equal to facilitate processing of the conduits.
It should be noted that, in addition, when the ground rail attitude control power system of the embodiment of the present application is applied, in order to avoid the pipeline from being corroded and rusted by water vapor, for example, a waterproof layer may be disposed on the surfaces of the gas circuit conduit 6 and the liquid circuit conduit 5. In order to prevent the waterproof layer from falling off, for example, the waterproof layer is closely attached to the surfaces of the gas path pipe 6 and the liquid path pipe 5, respectively, and is connected by an adhesive.
In this embodiment, the low pressure tank can be repeatedly replenished with high pressure tank propellant as needed to enable the entire system to once again be operational.
The foregoing is merely an illustrative embodiment of the present invention, and any equivalent changes and modifications made by those skilled in the art without departing from the spirit and principle of the present invention should fall within the protection scope of the present invention.
